Abstract

The invention relates to a device for cleaning pipelines and improves the reliability of the device when determining the location of a pipeline failure. A device for cleaning the drainage pipelines comprises a reactive housing with front and rear channels for discharging wash water. The device is equipped with an acoustic emitter in the form of resonant plates mounted concentrically to the housing on its outer surface. At the same time, in front of each plate in the housing there are holes, blocked by a piston fixed at one end of the rod, mounted with the possibility of axial movement in the front part of the housing. At the other end of the rod is installed stop, spring-loaded relative to the body. To register the acoustic signals produced by the resonant plates, the device is equipped with a receiver of acoustic signals.

Description

The invention relates to operational ameliorative technology, in particular to devices for cleaning pipelines.

The aim of the invention is to improve the reliability of the device.

The drawing shows a device for cleaning pipelines, a longitudinal section.

A device for cleaning the pipeline 1 comprises a flexible hose 2 connected to the housing 3. In the housing 3, reactive 4 and front 5 channels are made for the outlet of the washing water. An acoustic emitter in the form of resonant plates 6 is installed concentrically on the outer surface of the housing 3. Opposite each of the plates 6 in the housing 3 there are holes 7. In the front part of the housing 3, the rod 8 is mounted for axial movement. A piston 9 is fixed to the housing 3, which is made conical. At the other end of the rod 8, an emphasis 10 is mounted. To prevent the housing from being stuck in deposits on the pipeline walls 1, the diameter of the stop 10 exceeds the diameter of the housing 3. Between the stop 10 and the housing 3 is mounted spring 11.

The device is also provided with a receiver 12 of acoustic signals and a drill (not shown) for cleaning the pipeline 1 from blockage.

The device works as follows.

The device is manually driven at the mouth of the pipeline 1. Water is supplied through the hose 2 to the body 3 under pressure. Leaking from the channels 4 of the housing 3, the water creates a reactive thrust, pushing the device through the cleaned pipeline 1 and,

Channel 5, erodes and discharges 1 accumulated sediment from the pipeline. In the event of a malfunction in the pipeline 1, for example, a blockage, the piston 9 due to the force of the spring 11 acting on the stop 10 and the excessive pressure of water inside the housing 3 is in the extreme right position relative to the housing 3. The holes 7 are blocked by the disk 9.

When the device reaches a fault in the pipeline 1, the stop 10 stops as a result of the encounter with the obstacle. The housing 3 due to reactive gi continues to move forward, compressing the spring 11. At the same time, the piston 9 moves away from the front wall of the housing 3, opening the holes 7. Water leaking under pressure from them affects the resonant plates 6. By increasing the flow rate water from the housing 3 pressure inside it drops. This, in turn, reduces the reactive thrust of the casing 3. Under the influence of the spring 11, the casing 3 stops and then moves in the opposite direction. In this case, the holes 7 are again closed by the piston 9. The water supply to the resonant plates b is stopped. As a result of the decrease in the flow of water from the housing 3, the pressure inside it increases again, increasing the reactive thrust of the housing 3. The housing 3 changes direction and moves forward again, opening the openings 7. The cycle repeats. Due to the pulsation of water flowing out of the holes 7, the resonant plates 6 vibrate and emit an acoustic signal. Receiver 12 of acoustic signals from the earth's surface determines the location of the device in pipeline 1 and, consequently, faults in it, based on the highest value of the received signal. The water supply to the housing 3 is stopped. At the fixed location of the device, a hole is opened, the faulty section (link) of the pipeline 1 is removed. The blockage is removed from the pipeline 1 by the drill. The cleaned section of the pipeline 1 is installed in place. The hole is burrowing. Again in the housing 3

wash water is supplied. The device moves further along the cleaned pipeline 1. The cycle of operation of the device is repeated.

If the failure of pipeline 1 consists in displacing one relative to the other parts of the pipeline or in its destruction, then after the hole sections, this failure is eliminated by repairing the faulty section of the pipeline.

As a result of using the device, accurate determination of the location of the pipeline malfunction is provided, which reduces the amount of earthworks in the hole pit. The use of an acoustic emitter in the form of resonant plates in the device increases the reliability of the device when determining the location of a pipeline fault. Fast and accurate fault detection and improvement improves pipeline cleaning performance.
